In the summer of 1797, on Broadway near St. Paul’s Church in Manhattan, New York, Deputy Sheriff Robert Berwick, a male law officer, set out to do a routine and dangerous part of the job: serve a writ on a man named John Young and escort him toward a jailhouse so bail could be arranged. The task put them shoulder to shoulder in the open street, close enough for a sudden decision to become a death sentence.
As they walked, Young produced a pistol and fired a shot into Berwick’s chest. The wounded deputy fell, and Young bolted toward Barclay Street, still armed. A nearby resident, identified in later accounts as Mr. Thompson, rushed out after hearing the gunshot and confronted the fleeing man, who was carrying a pistol in each hand. In court testimony reported afterward, Thompson said Young answered him with a chilling confession—claiming he had done it “at the instigation of the devil”—before handing over the weapons and warning him to “beware.”
Young became the central and only named suspect in the killing, and the case moved quickly into the legal system. He was brought before a court, tried by a jury, and convicted of Berwick’s murder; the punishment was death. Records commemorating the fallen deputy note that Young was executed on August 17, 1797, and that Berwick left behind a wife who survived him.
The story did not end with the hanging. Two days after the execution, on the morning of August 19, 1797, people at Catherine Market were jolted into panic when human body parts washed up at Catherine Slip, sparking wild rumors of witches, cults, or a butcher turned killer. The grisly remains, however, were soon identified as John Young’s. Accounts tied to the aftermath describe how his sentence included dissection, and how physicians involved later explained that the bagged remains were disposed of in the river but were not properly weighted, allowing the tide to deliver them back to the city’s shoreline—an eerie coda that turned a courthouse killing into a waterfront spectacle.
